BATES Grain Length Derivations
Using Richard Nakka’s model for surface regression of a BATES grain: where or the initial web thickness. Then to achieve a neutral burn we want the initial to equal the final so: Substituting in for and simplifying: As Mr. Nakka points out, is constrained based on motor size and liner thickness and is constrained by…
